SIGNAL APPLIANCE.

Specification of Letters Patent.

Patented J an. i5, rare.

Application filed September 6, 1917. Serial No. 190,010.

To all whom it may concern:

Be it known that I, FrLirro Dr PIERO, a subject of the King of Italy, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Signal Appliances; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in signal appliances.

The primary object of the invention is to provide a starting compensator for the motors of machinery with means whereby a signal is sounded when the handle of the compensator is released.

Another object of the invention is to provide an attachment of this character which may be readily and easily attached to devices now in use, and which may be adjusted so as to fit them in the manner to produce the best result.

A further object of the invention is to provide a device of this character which will be simple, strong, durable and inexpensive in construction, one which will be efficient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and numerous other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawing forming a part of the application, and in which similar reference characters are used to designate like parts through the several Views:

Figure 1 is a front elevation of a device constructed in accordance with this invention, illustrating it applied to use; and,

Fig. 2 is an end view thereof.

Referring more particularly to the drawin gs, the letter a designates the starting compensator for the motor of a piece of machinery, said compensator being provided on the exterior of its casing with a pivotally mounted or swinging handle B. Arranged in the handle B at a point coincident with its pivot is a threaded opening, and disposed a short distance from this opening at a point remote from the pivot point is another threaded opening.

It is to be understood that the compensator a is of the kick out or rel type,

skilled I that is, the handle B and the parts on the interior of the casing associated with said handle are automatically released and caused to swing to their off positions when the current through the compensator and the motor and other machinery is turned OK for any reason.

The parts above explained form no part of the present invention, and are merely shown and described in making the use of the present invention clear.

Often times where there is steam operated and electrically operated machinery in the same factory or shop, and there are only a few persons operating such machinery, the noise from the steam operated machinery will prevent the persons in the shop from noticing the stopping of the electrically operated machinery should the current for operating the same be turned off accidentally or otherwise. In order to provide an efl'ec tive means for calling this to the attention of the persons in the shop, the present invention is devisedand to this end it consists of a signal pipe line 1, which in the present instance is provided with an inverted U-shaped bend disposed adjacent the compensator A. Arranged in a portion of this pipe line is a rotary valve 2. The stem of the valve 2 projects beyond its casing and is provided with a squared portion 3 which extends through a similar shaped opening arranged in one end of an arcuate arm l. A locking pin 5 is then extended through the squared portion 3 of the stem of the valve to hold the arm I upon the same.

The arm a is provided with a longitudinally extending or arcuate slot 6 through which extends a bolt- 7 carried by the lower end of link member 8. As clearly shown by Fig. 2 of the drawings, the bolt 7 is provided with suitable nuts 9 and washers 10 to firmly secure the bolt to the arcuate member 8 and to allow it to slide loosely in the slot 6. The link member 8 is thus loosely and slidably connected at its lower end to the arm 4.

The link member 8 is provided adjacent its other end with a rectangular shaped slot 11, said slot 11 only extending approximately a quarter of the length of the memher 8 where it joins a slot 12 having serrated edges which form in efiect a series of apertures.

The link member 8 is secured to the ban dle B of the pensator by a screw 13 through the slot 11 and by extending a screw 1% through one of the apertures which form the slot 12. 14 are anchored in the above mentioned openings arranged in the arm B. By this construction it will be seen that the arm B ls'moved'on its pivot, the'link member 8 will be swung simultaneously with the handle and will move or swing the arm L so as to open the valve 2, the loose connection of the- 1 opening. and into the opening in the handle.

stood-that I 'From the foregoing description, taken in connection with the accompanying drawings, the construction, use and operation of the device will be readily understood Without a more extendediexplanation.

As various changes in form, proportion,

and. in the minor details of construction may be resorted to without departing from the sp1r1t of this invention, it is to be underflop ies'of this patent may be obtained for five cents each, by addressing the These screws 13' and 1 moving the link do not wish to be limited to the construction herein shown and described other than as claimed.

I claim:

1. The combination with a handle pivoted at one end thereof, of a link member detachably, secured to said handle and adjustable longitudinally with respect to'thesame, a rotary valve stem, an arcuate arm fixed at one end to said valve stem, and means for loosely andzslidably one end of 'saidmember to said arm;

2. The combination with a handle pivoted: at one end thereof, of a link memberhaving: a longitudinal slot disposed at oneof its ends, said: slot extending only a portion of the length of said arm and joining another slothaving serrated edges forming a PlH- rality of apertures, pins. extending through one of said apertures and the first named connecting slot and anchored in said handle to locksaid' FILIPPO DI- PIEno;
